The first time Angie tries to say Neverfail's Battle Cry:
Angie: Liza Minnelli!
Near the end of Wyatt Crosses Over, the gang has stopped Maldark's Evil Plan and he dramatically declares "I will get you, Never Fail!"...only to linger on the crystal ball instead of making the grand exit that you would typically see here.
Dante: How do you hang this thing up? Maldark: You have to hang it up at your end, otherwise I cannot make another call.
When Angie brings her Glamazon friend/death-challenge rival over to HQ, Wyatt and Dante are terrified. Lyle, meanwhile, just checks his hair to make sure he looks good.
